Letters Patent No. 925381, dated August 31, V1869.

IMPROVEMENT IN CHURNS.

The Schedule referred to in these Letters Patent and making part of the same.

To all fwhom it may concern ing-wheel being removed, so as to more clearly illustrate the operating-mechanism.

Figure 3 is a plan view of the centre dasher.

Figure 4 is a plan view of one of the side dashers.

The nat-ure ot' my invention consists in passing horizontally, through openings in the ends of a suitable churn-box, a shaft, to which is permanently secured a centre dasher, composed of two tlat parallel tapering arms, connected by a short tube.

Around this shaft, and between the centre flasher and the sides of the box, are two side flashers, which are also secured to a tube, the diameter of this tube being such as to allow of its free revolution around the centre shaft.

These side das'hers are composed of a straight arm and double reversed L-arms.

The centre and side flashers are so connected with the shaft and side gearing, that when the churn is in operation, a reverse motion is imparted to the 'sa-me.

. Owing to thc diameter of the driving-wheel being so much greater than that of the intermediate gearwheels, it will readily be observed, that with but little power, au immense rate of' speed can easily he obtained.

In order to lessen, in a still greater degree, the labor of churning, I propose to forni the main drivingwheel of iron, and have it cast very heavy, so that it` will perform the double ottico of driving and balancewheel.

This churn has been practically tested, and experience has fully attested the fact, that owing to the system of dashers emphiycd, the immense velocity with which they are driven, and the fact that they travel circuits running in opposite directions, cnablcs me not only to success-hilly churn 1nilk,hut also to produce butter in one-fourth the time ordinarily required.

The great advantage of giving to the dashers thev movement stated, is that the reverse currents are thus brought together with such force that t-he globules will be dashed in opposite directions, and thoroughly broken, thus rendering the task of separating the fat and oily part of the milk from the cul-dy one of but little labor, l

and, at the same time, accomplishing it in the shortest space of time.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

A is the churn-box or body, which may be of any desired form. I prefer the circular, and constructed of either wood or metal. 1

This box A rests on suitable legs or other supports A* A, and is provided with a hinged top, A2.

a et are openings in the ends A A of the box.

Through these openings n a pass the tube-necks 1 4 b, which are connected with the pinions B B, working on the outside of the box.

Through these tube-necks b b and the opening in the centre of the pinion-wheel B passes a shaft, C.

The diameter of this shaft C is such as to allow of its free revolution in-the necks B B without imparting motion to the same.

D is the centre flasher, and is firmly secured to the shaft O, so as to revolve with it.

The form of this dasher D is clearly shown in lig. 3,

and consists of two Hat tapering arms (l d, connected by a short tube, d'.

These arms d d are of such width at their point of connect-ion with the tube d as to allow of suitable openings being cut in the former, for the reception of the ends of the latter.

The faces of these arms d l may be slightly scooped, which affords a better cutting-surface.

E E are two side dashers, and are permanently secured to the tube-necks b b, having openings in their centre, which pass over said necks.

These dashers are partly constructed on the same principle as the dasher D, being composed of straight arms e ci, parallel with each other, and connected by a tube, c2; but the distance between the arms c el is not so great as tha-t between the arms tl (l of the dasher D, and, besides, the inner arm e is connected with an L-shaped arm, e. .Theform of this flasher is clearly shown iu tig. 4.

lVhen the churn is in motion, the arms d d-pass' ends of the box, and around which revolve gearwheels G G.

This entire system of gearing 1s clearly shown in fig. 2.

The operation is as follows:

i wheels F F, the necks, B B' and dashers E E.

Having thus fully described my invention, v

What I claim vtherein as new, and de sire to secure by Letters Patent of the United States, is-

1. VThe driving-wheels F F, gear-wheels G G, pinion- Wheels B B, and shaft C, when the same are so combined and arranged that a double reverse motion is obtained by the revolution of the wheels F F, s that flashers that are attached to the shia-ft are cans d to travel in opposite directions, substantially as described. 2. The dashes D and E, when the former is permanently connected to the shaft G, and the latter to the tube-neck l), and both in such manner, that through the wheels B F G, they are caused to traveland work in opposite circuits, substantially as described. In testimony whereof, l have signed my naine to this specification, in the presence of two subscribing witnesses.
